Since the early 1900s, industries along the lower Willamette River have released dozens of contaminants into the river and onto the land around it. Substances released include polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), metals, pesticides (e.g., DDT), dioxins, and furans. Many of these contaminants can harm the environment for many decades. Even small amounts of these contaminants can be hazardous to fish and wildlife. Larger animals like osprey and river otter that have eaten contaminated smaller animals (e.g., fish) can build up high levels of contamination through their food.
In 2000, Portland Harbor was declared a federal Superfund site. The Superfund study area extends from river mile 2 (between the Multnomah Channel and Columbia River) to river mile 11.8 (near the Broadway Bridge). The EPA is expected to issue a decision about cleanup of contaminated river sediments in 2012 while the Oregon Department of Environmental Quality is working to reduce the amount of contamination entering the water from the land.
In 2002, the Portland Harbor Natural Resource Trustee Council (Trustee Council) was formed to develop and coordinate damage assessment activities at Portland Harbor and to plan for the restoration of natural resources through the NRDA process. The NRDA process is separate from the EPA clean-up activities. Under NRDA, the Trustee Council will evaluate how the natural resources were harmed over the time that the area has been contaminated and will develop a restoration program to compensate for those losses.
Portland Harbor Trustee Council
When natural resources are injured by releases of hazardous substances or oil, laws such as the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and the Oil Pollution Act empower natural resource Trustees to obtain compensation for harm to trust resources and to plan and carry out actions to restore injured resources through a process called natural resource damage assessment (NRDA).
The Trustee Council currently consists of representatives of eight Trustees:
